V E LOGI P E D E Specification of Letters Patent.

Patented Oct. 31, 1905.

Application led March 29, 1905. Serial No. 252,698.

To @ZZ whon t 71u13/ concern:

Be it known that I, CURTIS G. KRANZ, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inVelocipedes, of which the following is a specification.

My invention relates to improvements in velocipedes, and is fullydescribed and eX- plained in this specification and shown in theaccompanying drawings, in which Figure l is a top plan of my improveddevice. F ig. 2 is a side elevation thereof, and Fig. 3 is a rearelevation.

Referring to the drawings, A is a bifurcated frame having a forwardcentral extension a, terminating in a head a', and two rear eXtensionsa2.

B indicates a front fork which extends downward from the head a', saidfork having journaled at its lower end a wheel C and having at its upperend a pivoted steering-handle D, arranged to swing in the plane of thewheel C. Between the rear ends of the rearwardly-extending member t2 ofthe frame A is journaled a shaft E, having at its center a crank c andat its ends wheels E'.

Near the center of the frame A is an upwardly-projecting bracket F, inwhich is pivoted a beam G, having near its rear end a downward curve oryoke g, passing under a foot-rest H, secured to the frame A. At the rearend ofthe beam G is a seat I, connected by a pitman J with the crank con the shaft E. At the forward end of the beam G is secured a secondseat K, and in front of said seat and below the same is a footboard L,secured to the frame.

In operation two persons occupy the seats of my improved device withtheir feet on the corresponding footboards. lThe front seat K islongitudinally adjustable on the beam, according to the weight of thetwo users, until they balance each other, and the handle D, which, itwill be noted, is adjustable in length, is arranged to be within easyreach of the passenger on the front seat. Thereupon the device can bepropelled forward if the passengers will press downward on thecorresponding footboards alternately, the beam meanwhile reciprocatingon its pivot, so that a seesaw motion is obtained in addition to theforward one, the oscillatory motion of the beam being transmitted to arotary motion of the shaftlE by the pitman and crank.

I realize that considerable variation is possible in the details of thisconstruction without departing from the spirit of the invention, and Itherefore do not intend to limit myselil to the specific form hereinshown and described.

I claim as new and desire to secure by Letters Patent- In a device ofthe class described, the combination with a frame and wheels supportingthe same, of a beam pivoted between its ends to the frame, a downwardcurve in the rear portion of the beam, a footboard secured to the frame,under which said curve passes, seats secured to the ends of the beam andmeans of connection between the beam and the wheels.

In witness whereof I have signed the above application for LettersPatent, at Chicago, in the county of Cook andState of Illinois, this25th day of March, A. D. 1905.
